Specific embodiment

The present invention is described in detail below with reference to the accompanying drawings and embodiments.

As shown in Figure 1, the present invention provides a kind of automation cap rotating device of radioactive sample bottle, including power source, connection Axis device 3, uncap first 4, clamping component 5 and lifting part 6；The power source drives first 4 rotation of uncapping by shaft coupling 3；It is described Clamping component 5 and lifting part 6 act on container to be uncapped with cooperate first 4 rotation of uncapping make the lid of container to be uncapped with Container body separation.

The first 4 elastic-friction components 402 for including skeleton 401 and being at least partly coated on outside the skeleton 401 of uncapping； The elastic-friction component 402 can clamp lid after by the lid compressional deformation.The elastic-friction component is by gathering Urethane material is made.Embedded using stainless steel insert in the present embodiment, polyurethane is wrapped up in outside, after polyurethane wraps up, has very Big elasticity and friction can effectively clamp bottle cap in spiral cover, and bottle cap separated with body after guarantee lid will not It falls, which greatly simplifies bottle cap clamping device, simplifies maintenance mode.First 4 are uncapped for clamping the lid Part is gradually smaller opening from outside to inside, so that bottle cap protrudes into.

Seal closure is provided with outside the power source；The seal closure includes cover 1 and sealing cover lid 2 interconnected；It is described 302 airtight connection of bearing of cover bottom 301 and the shaft coupling 3.In this way, entire power source is in the protection shape of sealing State avoids radioactive pollution, safeguards convenient for power source.The power source is the servo motor with torque sensor.Controller By the rotation torque for the real time monitoring signals bottle cap that torque sensor transmits, and judge whether bottle cap completes screw capping by torque With uncap, if it is abnormal that stripped thread etc. has occurred.

As shown in figure 3, the shaft coupling 3 includes bearing 302 and connector；The connector pass through the bearing 302 with It first 4 is connect with power source and uncapping respectively at its both ends；Sealing ring is provided between the connector and the bearing 302 (306、307)。

Connector includes the first connector 303, the second connector 304 and the third connector 305 of coaxial arrangement；Described A connection piece 303, the second connector 304 and third connector 305 are sequentially connected；The third connector 305 also extends through described Second connector 304 is connect with the first connector 303；First connector 303 passes through the bearing 302；The power source It is connect with the first connector 303, uncap first 4 connect with third connector 305.In the present embodiment, realized by three connectors The design of quick change construction, can easier completion uncap first 4 replacement, and the bottle cap of different size can be adapted to.Meanwhile first connects The connection type of part 303, the second connector 304 and third connector 305 forms Compressible structure, and sample can be effectively prevented Bottle cap badly and is effectively monitored the variation of real-time torque and angle by crushing.

In the present embodiment, 3 material of shaft coupling uses stainless steel material, four upright supports of structure type, safety and firmness.

The sealing ring is at least two, is set between first connector 303 and bearing 302, in this way, shaft coupling Two-stage rotatory sealing is used between 3 and power source, sealing ring material is polytetrafluoroethylene (PTFE), can effectively prevent radioactivity gas in glove box Contact of the body with power source, later maintenance can directly carry out the replacement of power source, radioactive substance avoided to leak.

In the present embodiment, the power source, shaft coupling 3 uncap first 4, clamping component 5 and lifting part 6 is separately mounted to The different location of same bracket 7 is to ensure described to uncap first 4, clamping component 5 and lifting part 6 cooperates accurately.

According to the size of different sample bottles, different size may be selected uncaps first 4, meets the spiral cover of different size sample bottle Demand.It can be applied to the Rapid opening that rabbit bottle is run in spentnuclear fuel reprocessing plant analysis glove box, it is expansible severe applied to other Spiral cover application scenarios under environment.

Through testing, the automation cap rotating device for the radioactivity bottle that present embodiment provides, it can be ensured that uncap every time Later, bottle cap is not fallen, and is thoroughly separated with bottle body, and closing lid ensures that final tightening result is consistent and reaches setting torque value.

It uncaps process:

The fixed position for running rabbit bottle of the clamping component that race rabbit bottle is placed on the machine of uncapping, clamping component is tight by race rabbit bottle clip, At this time power source start, power source start while, lifting part will run rabbit bottle rise, when lifting part rise in place, spiral cover Start (as shown in Figure 4), delay after a certain period of time, controls lifting part free-falling, completes wait uncap, by lifting part Gravity separates race rabbit bottle cap thoroughly with bottle body, and each component is kept in the center (as shown in Figure 5), and the process of uncapping terminates.

Closing lid process:

Rabbit bottle will be run to put to position is fixed to clamp, clamping component movement is clamped race rabbit bottle, and lifting part rises, power Source drives and uncaps a screw capping, when detecting that bottle cap torque reaches expected torque value (being set as 0.8NM in the present embodiment), uncaps Head stops rotating, lifting part decline, lifting part in place after, clamping component movement makes to run rabbit bottle in relaxation state, closing lid It completes.

Abnormal conditions (stripped thread):

During device carries out closing lid, head of uncapping, which is in, continues rotation status, and the torque value of real-time detection is predetermined (it is set as 10 seconds in the present embodiment) in time and is unable to reach preset value (0.8NM), then is determined as that stripped thread occurs in the race rabbit bottle State, can not tighten bottle cap, and equipment carries out exception information alarm.

Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art Mind and range.If in this way, belonging to the model of the claims in the present invention and its equivalent technology to these modifications and changes of the present invention Within enclosing, then the present invention is also intended to include these modifications and variations.
